Rack mount safety instructions

Operating Temperature

The operating ambient temperature of a rack environment may

be greater than room ambient if installed in a closed or multi-unit

rack assembly. Therefore, you should install the equipment in an

environment compatible with the maximum ambient

temperature of 40° C.

Reduced Air Flow

You must not compromise the airflow required for safe

equipment operation when you install the equipment in a rack.

Mechanical Loading

Mounting of the equipment in the rack should be such that you

do not cause a hazard due to uneven mechanical loading.

Circuit Overloading

Consider the connection of the equipment to the supply circuit

and the effect that the overloading of the circuits might have on

current protection and supply wiring. You must also consider and

use the equipment nameplate ratings when you address this

concern.

Reliable Earthing

You must maintain reliable earthing of rack-mounted equipment.

Pay particular attention to supply connections other than direct

connections to the branch circuit (such as using power strips).

Do not attempt to open the case of the appliance. If you do, you incur a high risk of electrical shock that

may cause damage to the appliance or personal physical injury or death to you and/or others. No user-

serviceable parts exist inside the appliance. If you open the appliance case or make unauthorized

changes to the case, ViewCast voids your warranty.

Install the appliance away from any heat sources. This remains vital to the safety of the product users.

Do not install the appliance near any heat sources such as:

 Radiators

 Heat registers

 Stoves

 Other heat-producing equipment

WARNING! Installing the appliance near heat sources could result in personal injury or death.

Never insert objects of any kind into the appliance through any appliance openings, as the objects

may touch dangerous voltage points, short out parts, and result in a risk of fire or electrical shock.

Do not stack the appliance atop or below other electronic devices as this can cause heat build-up and

vibration of the appliance. These conditions can damage the appliance thereby voiding the limited

warranty.

You may stack multiple Niagara 4100 units as these appliances accommodate stacking.

Do not install the appliance in any area where the temperature is less than 5°C or more than 40°C.

Transfer from temperature extremes may cause condensation. Let the appliance remain unplugged at

room temperature for at least 45 minutes before connecting it.

Use an outlet with surge suppression or ground fault protection when using the appliance. Unplug the

power cord from the wall outlet and disconnect the lines between the appliance and the video source

for added protection:

 During a lightning storm

 During dangerous weather conditions

 When the encoder remains unattended or unused for long periods

Reduce the risk of fire or electric shock. Do not expose the appliance to any rain or moisture. Exposing

the appliance to rain or other types of moisture could result in appliance damages. Do not place any

liquids on or near the appliance. If you place liquids in any form on or near the appliance, do so at your

own risk, for you incur a high risk of electrical shock that could occur and cause damage to the

appliance.

WARNING! Exposing the appliance to rain or other types of moisture could result in physical injury or

death. Any liquids on or near the appliance may result in electrical shock and personal injury or

death.

adaptor or turn off the car engine before you turn off the player. Doing so may damage the player.

Do not attempt to service the appliance yourself. If you open or remove covers, you may be exposed to

dangerous voltage. Such action voids the Limited Warranty. Refer all servicing issues to authorized

service personnel only.

The plug-socket combination that serves as the main disconnecting device must be accessible at all

times.

Protect the power cord from anyone walking on it and being strained or pinched particularly at plugs,

electrical receptacles, and the point where the power cord exits the appliance.

Do not use adapter plugs or remove the grounding prong from the power cable.

Use only the type of power source indicated on the marking label on the back panel of the unit to

operate the appliance. Unplug the appliance power cord by gripping the plug and removing it from the

power source. Do not pull the cord to remove the power source from the appliance.

Do not plug the appliance into a wall outlet that contains an overload of electrical cords or power

strips/extension cords. This type of overload may result in fire or electrical shock risks.

ViewCast 11

If any components are missing or damaged, do not continue with the installation. Contact the ViewCast

reseller from which you purchased your Niagara 4100 streaming media appliance for assistance in

obtaining any missing parts or for parts replacement.

System requirements

Ensure your computer meets the following system requirements.

 4 GB RAM or larger

 HDD (160 GB or larger)

 Osprey 710e HD technology

 4.5” H x 8” W x 12” D)

 8 lbs (3.6 kg)

 90 W power supply

Installing additional software

The Niagara appliances run an embedded version of the Microsoft Windows 7 operating system (OS),

which is a sub-set of the normal retail version. The Microsoft License agreement limits the use of the

system to what the machine is designed to do.

The Microsoft Update process is turned off by default to prevent interruptions during live streaming

events. It is also not advised to use a Windows 7 installation CD to add features to the system or the

appliance may fail.

You may load additional software on the appliance; however, ViewCast does not support this additional

software. You also need to ensure the primary drive is not full or the appliance will fail. In the event of a

problem, you may need to perform a Factory Restore, which returns the appliance to the original

software load. You may save the current encoder profiles and reload them when the Factory Restore is

complete.

You can perform a Factory Restore at any time. This process returns the appliance to the software load

that came with the appliance. Perform a Factory Restore if the appliance becomes unstable due to

installed applications, viruses, etc. Please refer to the user guide for instructions.

ViewCast Support can provide assistance should the appliance fail to start. In most cases, you can

restore an appliance to operation without returning it to ViewCast. There is a fee in the event a user

returns an appliance due to applications the user installed or if the appliance failed because the primary

partition (drive C) is full.

Connecting to the Internet

The Internet is a dangerous place. Never connect a Niagara appliance directly to the Internet. Always

use a router. A basic router is sufficient to protect the appliance and you can configure the router as

needed to forward specific ports to the appliance. The router’s bandwidth should match or exceed the

speed of the appliance’s network card.

The Shields Up test by Gibson Research (http://www.grc.com/intro.htm) is a good utility to verify you do

not expose the Niagara appliance to the Internet. Select to test All service ports. The utility queries the

appliance’s outside IP address for all service ports less than 1056. All of these ports should report as

Stealth and the analysis should show the tests have passed. Ports the router has forwarded show as

open. This is OK and you should consider the test as passed.
